Noble Paul commented on SOLR-6787:
----------------------------------

bq.That's my entire point... if it's hard to do X, look first into making X 
easier 

We should do that too. 

But it does not solve the problem


bq.If it's easier to manage blobs this way

It won't be. Why would anyone want to store a blob and all the past versions of 
it normally? 

I'm trying to dedupe a blob here , is it required normally ?

I'm trying to ensure that there is always a name for a blob  , is it required 
normally ?

bq.Another option would have been to do it in a branch first, esp if it's 
exploratory.

It is not exploratory . This is a feature we need 

bq.Trying to reuse and improve existing APIs before creating new ones, or 
making new APIs as generic as possible does not run counter to that 

As I said earlier I'm fully convinced about the need of this API. At the same 
time I'm open to suggestions to improve it. 
We do an exploratory branch when we have a doubt on how to implement it. In 
this case , the question is about the interface which requires discussion not 
another branch

> A special collection called .system needs to be created by the user to 
> store/manage blobs. The schema/solrconfig of that collection need to be 
> automatically supplied by the system so that there are no errors
> APIs need to be created to manage the content of that collection
> {code}
> #create your .system collection first
> http://localhost:8983/solr/admin/collections?action=CREATE&name=.system&replicationFactor=2
> #The config for this collection is automatically created . numShards for this 
> collection is hardcoded to 1
> #create a new jar or add a new version of a jar
> curl -X POST -H 'Content-Type: application/octet-stream' --data-binary 
> @mycomponent.jar http://localhost:8983/solr/.system/blob/mycomponent
> #  GET on the end point would give a list of jars and other details
> curl http://localhost:8983/solr/.system/blob 
> # GET on the end point with jar name would give  details of various versions 
> of the available jars
> curl http://localhost:8983/solr/.system/blob/mycomponent
> # GET on the end point with jar name and version with a wt=filestream to get 
> the actual file
> curl http://localhost:8983/solr/.system/blob/mycomponent/1?wt=filestream > 
> mycomponent.1.jar
> # GET on the end point with jar name and wt=filestream to get the latest 
> version of the file
> curl http://localhost:8983/solr/.system/blob/mycomponent?wt=filestream > 
> mycomponent.jar
> {code}
> Please note that the jars are never deleted. a new version is added to the 
> system everytime a new jar is posted for the name. You must use the standard 
> delete commands to delete the old entries
